07/07/11 No of stories , one is ideal as against limitations of space, cost of land Height utilization , principle of cubic space, principle of ‘go vertical’, limitation on height utilization due to fire safety and insurance regulations  2. Handling Technology  Movement continuity Reducing runs Reducing short runs with intermediate stops Ensuring longer runs
Movement scale economies Movement in large bulk Moving material in cases strapped on pallets or  Containers  Handling technology is addressing these issues 07/07/11

07/07/11 Inventory at various locations,  the square root law Inventory reduction and customer service How much to hold and in how many locations to hold? The square root law X 2  =[X 1 ] [√n 2 /n 1 ]  X 1  = total inventory in existing facilities  X 2  = total inventory in future facilities
07/07/11 n 1  = number of existing facilities [warehouses] n 2  = number of future facilities [warehouses]   If a company distributes 40,000 units using 8 existing facilities and plans to reduce  the inventory in their future facilities to 20,000 units,  then what should be the number of facilities in their future network without compromising the customer service? If we use the square root formula, the answer is 2 facilities
